The B-Lig, (English: B-League),is the top men's football league in Birgeshir, run by the VFAB. Birgeshir doesn't have cities as it is currently an extra-territorial micronation but it aspires to become territorial at least in a house. For this reason,the eight teams which play in the B-Lig represent some rooms of a common house (like other sport leagues in Birgeshir).
The league consists of 8 teams, split into two four-team conferences (Day Conference and Night Conference). Each team faces the other teams twice. At the end of the regular season, the team with the highest point total in the overall table (Day + Night Conference) is awarded the Old Shield (which echoes the inaugural season format and the practice of most of the Micras leagues). The regular season is followed by the Conference Finals where the top two teams of each conference play for the Conference Championship one time. At the end of the Conference Finals,the Day and Night champions will face each other in the B-Lig Grand Final (Birgesh: B-lig Büjük Final). The season begins in January and ends in May with games played on Sundays. There is no relegation or promotion system in the league.
The B-Lig was founded in July 2012 after Birgeshir's Micrasian claim was successful. The first season kicked-off on 15 July 2012 with six teams in a round-robin tournament and without Conferences and playoffs. From the second season,the B-Lig introduced two new teams (Öturma FK and Koridor Balan FK) and a new format.

Clubs are permitted to place a golden star badge above their crest on their uniforms for every five national championships won.
The B-Lig Championship title is represented by a waving birgesh flag patch and the winning team will bear it on the uniform in the following season. This is similar to the italian "scudetto".
